Question

这个python文件的目的是读取类似于下面的文件，修改具有＆＃34; PL＆＃34;的行。在形状领域。我遇到的问题是OK框正在流入初始文件选择按钮。此外，OK按钮不会显示在初始复选框中，也不会使用＆＃34; PL＆＃34;更新第一行。在里面。一旦第一个复选框和文件选择框被Xed输出，该复选框似乎按照预期的第二行开启。有人可以帮我解决这个问题吗？它应该调出文件选择框，选择要打开的文件，选择要保存的文件。此框应保持打开状态，复选框应打开。一旦你做出选择，它应该一次又一次地打开，直到没有更多的行具有＆＃34; PL＆＃34;在他们中。新文件应该在正确的位置添加数据。

这是在阅读文件＆＃34; 1288.kss＆＃34;。将文件另存为＆＃34; 1288r.kss＆＃34;

Answer 1

在根窗口被销毁之后，您对CheckVar1.get()等的调用会发生，在这种情况下，变量也会被销毁。

在销毁根窗口之前，必须调用get方法来响应事件，而不是在根窗口被销毁之后立即调用。
